In view of the single invalid data of the optoelectronic deflection meter system in the engineering practice of the bridge structural health monitoring system, which bring the illusive alarm and can not be identified by the traditional methods of signal processing and data analyzing,the paper analyses the characteristics of the single invalid data, and formalizes and describes them.

针对在大型桥梁结构状态监测系统工程实践中，光电挠度测量系统采集的数据中存在的较多单点失真数据无法使用传统的信号处理与数据分析方法过滤的问题，本文在连通管式光电挠度测量系统原理基础上，深入分析了系统中单点失真数据的特点，对单点失真数据进行形式化描述和说明，从而提出了一种基于数据速率变化来过滤单点失真数据的滤波方法。

Now do we must discuss are not need to change,Should study,How but is you should quickly study,More accurate diastrophism,Only was invariable possibly is changes,Moreover or fast \ initiative diastrophism,Draws a inappropriate analogy,In the past everybody said ten years rub a sword, today we perhaps still needed for ten years to rub a sword,What but is different is we while rubs a sword also to want each hour to make to beat a dog the stick Otherwise, your sword does not have 磨出 to come, the neck on is wiped by yours enemy,Otherwise, the sword 磨出 has come also is the toy The competition is the war,I thought this selected already no need to doubt,The present age, the plagiarism and the surmounting speed nearly already was the speed of light, the people do not even have the time calmly to get down the personal status own achievement.

请高手按照演讲的体裁来翻译：如今的年代我们所要讨论的不是需不需要变化，应不应该学习，而是你应该如何更快地学习，更准确地变化，唯一不变的可能就是变化了，而且还是快速地\主动地变化。打个不恰当的比方，过去大家都说十年磨一剑，今天我们也许仍然需要十年磨一剑，但是所不同的是我们在磨一剑的同时还要每小时制造一根打狗棒。否则，你的剑还没有磨出来，脖子就被你的敌人抹了，而且我们在磨剑的间隙里，要不断地\想方设法地了解一下我们磨剑的方法是否先进，否则，剑磨出来了也是玩具。竞争就是战争，我想这点已经没有什么需要置疑的了。

Present a new LVQ wavelet image coding algorithm in which entropy coding and enumeration codes of different length are utilized. For wavelet image coding, there is a problem of mismatch between lattice distribution and the input vector probability density function in traditional LVQ algorithms (such as product-code pyramid VQ and piecewise uniform LVQ).

采用准稳态的极化试验研究了各主要试验参数对碳钢在3%NaCl溶液中点蚀电位的影响，结果表明：3种碳钢钝化的临界pH值约为8 0 ；当T =2 0℃～35℃时，点蚀电位值Eb10 0 随温度的降低而变正；当电位变化速度慢于30mV/ 30s时，Eb10 0 随电位变化速度的减小而变负；试验面的粗糙度越大，点蚀电位越

In this paper the tracking algorithm based on heuristic search is proposed.The starting point is positioned according to the trapezia matching model,gray change property of lane markings and the restraint of real lane width.Then we search the lane edge point from the start point with the tolerance cost rule function.

提出一种边界点启发式搜索算法，根据梯形匹配模型、车道线灰度变化特征和实际车道宽度约束，确定搜索的起始点，从起始点根据度量代价准则函数搜索车道边界点。

More recently, singular optics has been extended to polychromatic cases by Professor Wolf and his co-workers, in which they have showed that drastic spectral changes occur in the vicinity of intensity zeros in the focal region of polychromatic, spatially coherent, converging spherical waves, i.e. the spectrum is redshifted at some points, blueshifted at some other points, and is split into two peaks elsewhere.

最近，Wolf教授和他的同事们指出：在多色空间相干会聚球面波焦点区域振幅等于零的点附近会发生剧烈的光谱变化，即在一些点处光谱为红移，在另一些点处光谱为蓝移，在其它点处光谱则分裂为双峰结构。

本文从操作的角度求解并分析换热网络结构已定或网络正在运行情况下的操作夹点，定性分析操作夹点的变化规律，并提出在操作夹点附近设置旁路实现网络的旁路优化控制，从而将夹点技术应用于换热网络旁路优化控制中。

Basic characteristics of cosine transform spectrum were analyzed, where contour lines of 2D cosine transform of point mass present the shape of a quarter of concentric circles and the number of counter become small along with the increasing of wave numbers.

分析了点质量和直立矩形柱体重力异常余弦变换谱的基本特征：点质量二维余弦变换谱等值线呈1/4同心圆形状，等值线随着波数的增大而变稀；直立矩形柱体谱出现了周期性变化的零等值线，该等值线将非零等值线划分为a×b个矩形区域，而且等值线值在各矩形型区域中正负交替变化，随着波数的增大，不同的矩型域中等值线值呈e指数衰减特征。

In order to distinguish these two types of transitions, a state recognition method is introduced. We firstly propose a variable contact set in which the contact points on the robot body are defined to represent the alternation of the contact states logically. Then, by predefining thresholds for the contact forces, the state transition can be well recognized.3 As another research topic, the local tracking control according to the pre-acquired state transition trajectories plays an important role in realizing the non-regular motion for the humanoid robot.

在状态转换识别方法上，本文提出了接触点集合的概念，对接触状态的变化进行逻辑上的表达；再结合接触点集合的变化情况，通过设定接触力阀值来实现对状态转换的识别。3根据给定的状态转换轨迹进行局部的跟踪控制，是本文实现类人机器人非规则运动的另一个重要研究内容。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
